Verified step by step guidance1
Begin by identifying the type of molecule NH3 is. Ammonia (NH3) is a polar covalent molecule due to the difference in electronegativity between nitrogen and hydrogen atoms.
Understand that the major electrostatic force between ammonia molecules is not a bond within the molecule, but rather an intermolecular force between separate molecules.
Recognize that ammonia molecules exhibit hydrogen bonding, which is a type of dipole-dipole interaction. This occurs because the nitrogen atom is highly electronegative and attracts the hydrogen atoms from neighboring ammonia molecules.
Hydrogen bonds are stronger than other types of dipole-dipole interactions due to the presence of hydrogen atoms bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.
Conclude that the major electrostatic force between ammonia molecules is hydrogen bonding, an intermolecular force, rather than any type of ionic or covalent bond within the molecule itself.
